Title: Dyeing of cellulose ester and ether textile materials
IPC: D06P1/649
Filed: 1949-04-14
Abstract: Textile materials wholly or partly composed of a cellulose ester or ether are treated with N,N1,N11-triphenyl-guanidine before, during or after dyeing in order to enhance the resistance of the dyeings in order to enhance the resistance of the dyeings to gas fading.  The N,N1,N11-triphenyl-guanidine may be applied in dispersed form from an aqueous medium, preferably in the presence of a dispersing agent. The invention is of particular value when dyeing with anthraquinone dyestuffs containing free amino, alkylamino or arylamino groups, and includes a composition comprising N,N1,N11-triphenyl-guanidine and a cellulose acetate dyestuff of the anthraquinone series.  In examples, (1) cellulose acetate material is dyed from a bath containing 1,4,5,8-tetraaminoanthraquinone and N,N1,N11 - triphenyl - guanidine in aqueous dispersion, or the material is first dyed and then treated with the dispersion of the guanidine-derivative; (2) cellulose acetate is dyed as in (1) using a dispersion prepared by tumbling N,N1,N11 - triphenyl - guanidine with gravel in the presence of a dispersing agent drying and grinding in the presence of isopropyl-naphthalene sodium sulphonate, and (3) a cellulose acetate/viscose or cellulose acetate cotton union textile material is dyed from a bath containing a dispersion of 1,4,5,8-tetraaminoanthraquinone, a direct orange dyestuff C.I. No. 326 and N,N1,N11-triphenyl-guanidine whereby a two-colour effect is obtained.  Specification 340,572 is referred to.

Title: Improvements in and relating to stabilisation of esters
IPC: C07C69/80
Filed: 1962-03-16
Abstract: The stability to heat and oxidation of fully esterified carboxylic or phosphoric acid esters is increased by treating the ester with an aqueous solution of ammonia or amine at from 130-200 DEG  C. and at elevated pressure. In addition to the amount of ammonia or amine to neutralize any excess residual acidity of the ester, the maximum used is from 0.1 to 5% by weight of the ester.  Esters used as synthetic lubricants or plasticizers, e.g. alkyl phthalates, isophthalates, terephthalates, adipates, azelates, sebacates, phosphates, citrates and pyromellitates, aryl phosphates, methylene glycol dicaproate, dipropylene glycol dibenzoate, pentaerythritol tetrahexoate and glycerol tripeptanoate are treated and the amines mentioned are mono-, di-, and triethylamines, mono-, di-, and trimethylamines, monoisopropylamine, mono-, di-, and triethanolamines and isopropanolamines, morpholine, piperidine and hydroxyethyl-ethylenediamine.  Examples describe the stabilization of di-n-heptyl phthalate with ammonia, and with mono- and diethanolamine, di-n-butyl phthalate with monoethanolamine, di-decyl and di-nonyl phthalate with ammonia, and di-ethyl-2-hexyl sebacate with ammonia.ALSO:Lubricating compositions and transmission fluids comprise esters which have been stabilized against heat and oxidation by treating with an aqueous solution of ammonia or of an amine at from 130 DEG  to 200 DEG  C. under elevated pressure in a proportion of 0.1 to 5% by weight of ester, in addition to any required to neutralize residual acidity (see Division C2).  Alkyl phthalates, isophthalates, terephthalates, adipates, azelates, sebacates, phosphates, citrates and pyromellitates, and methylene-glycol dicaproate, dipropyleneglycol dibenzoate, pentaerythritol tetrahexoate or glycerol triheptanoate in particular di-n-heptyl, di-n-butyl, ethyl - 2 - hexyl, didecyl and di - nonyl phthalates are mentioned.  Di-ethyl-2-hexyl sebacate treated as above and with phenothiazine as inhibitor is used as a lubricant.

Title: Improvements in or relating to secondary-electron-emitting discharge devices
Inventor: BULL CABOT SEATON
IPC: H01J43/16
Filed: 1947-04-18
Abstract: 644,012. Electron multipliers. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 18, 1947, No. 10319. [Class 39 (i)] An electron multiplier comprises a thermionic cathode, a control electrode, a secondaryelectron-emitting electrode (dynode), a further dynode, and a collecting electrode (anode), the arrangement being such that the beam of primary electrons emitted by the cathode is projected at such an angle as to pass to one side of said further dynode and impinge on the first dynode to release secondary electrons which converge on said further dynode. In the arrangement shown, comprising duplicate further dynodes and anodes, the cathode 1 at earth potential is rectangular in section, the wider sides being electron-emissive, and is surrounded by a wire-wound control electrode 2 at a suitable negative potential supported by rods 3, and a wire-wound accelerating or screening electrode 4, at a positive potential of about 150 volts, supported by rods 5. The first dynode 6 consists of a continuous sheet of metal of elliptical section as shown, maintained at a positive potential of about 250 v., and has a coating of secondary - electron - emissive material on the areas where primary electrons impinge. The two further tubular dynodes 7 and 8 are at positive potentials of about 400 v., and are surrounded by wire-wound helical anodes 9 and 10 at positive potentials of about 600 v., supported by rods 11 and 12 respectively. The capacity between the anodes 9 and 10 and the control electrode 2 is substantially eliminated by the provision of channel-shaped shields 16 which are attached to rod-shaped focusing electrodes 13 and 14 maintained at cathode potential or at the potential of the accelerating electrode 4, or the shields may be attached to the accelerating electrode. The cathode may be of elliptical 'section, in which case the control and accelerating electrodes are also elliptical, or the cathode may be circular, in which case the control and accelerating electrodes are shaped to have a major and a minor axis, and two channelshaped beam-forming electrodes are provided adjacent opposite ends of said major axis. In a modification designed to reduce the length of the leads required to connect the dynodes 7 and 8 and the anodes 9 and 10 together, half of the arrangement shown in Fig. 1 is replaced by the mirror-image of the remaining half taken along the plane containing the longitudinal axis and the major axes of the cathode and the control and accelerating electrodes. A single channel-section screen only is then required. Specification 532,082 is referred to.

Title: Improvements in or relating to hydraulic braking systems for motor vehicles
IPC: B60T8/26

Abstract: 768,764. Hydraulic brakes. TEVES, H., and TEVES, E. A., [trading as TEVES MASCHINEN - UND ARMATURENFABRIC KOMM-GES., A. April 12, 1955 [May 29, 1954], No. 10539/55. Class 103 (1). In order to allow for the effect of increased axle loading of the front wheels of a vehicle when severe braking conditions exist; the hydraulic braking intensity to the rear wheel brakes may be reduced to prevent locking of the rear wheels by inserting in the brake conduit to the rear wheel brakes a regulating valve for regulating the rear wheel brake pressure via a spring-loaded piston, the regulating valve having a part thereof bearing on the piston-rod and a compression spring being located between the piston-rod and the part which bears on the piston-rod. Fig. 1 shows one embodiment where the regulating valve consists of a housing 1 in which a piston 2, under the influence of pressure means, actuates a spring- loaded valve 4 via a piston-rod 3. Up to a pressure determined by the springs 7 and 9 the pressure prevailing in the brake conduit is transferred unaltered to the rear wheel brakes cylinders via bore 5, chamber 13, pipe 12, through open valve 4 into chamber 14 and bore 6. When the pressure in the brake conduit increases to a value exceeding the pressure exerted by the springs 7, 9 the piston 2 and the valve 4 are displaced to the right. The pressure transfer from chamber 13 to chamber 14 is thus throttled by the displacement of the valve 4. Fig. 2 illustrates an alternative construction wherein the external pipe 12 is eliminated; pressure from the master cylinder being supplied via bore 18 into chamber 26 and via open spring-loaded valve 17 slidable on piston-rod 21 into chamber 27 and via bore 19 to the rear wheel brake cylinders. In this case the tension spring 15, acting on the piston 16, may be adjusted by screw 25.

Abstract: 992,176. Storage display tubes. TEKTRONIX Inc. March 18, 1963 [March 19, 1962], No. 10659/63. Drawings to Specification. Heading H1D. A storage display tube has a single direct viewing screen for storage and display, comprising a light transparent conductive support of tin oxide applied to the face-plate of the tube (over a fused glass graticule), and covered with a thin storage dielectric layer of phosphor material, e.g. Zn 2 SiO 4 : Mn. A positive charge image is formed thereon by a high velocity beam writing gun 52, Fig. 4 (not shown), causing secondary emission from the layer and a pair of flood guns 76 causing continued secondary emission, and the production of a corresponding light image. A further " contrast enhancement " gun 92, Fig. 6 (not shown) may be mounted between the flood guns 76. An alternative arrangement of the storage target, Fig. 9 (not shown) comprises a layer of glass frit 114 between the phosphor and conductive layer to increase contrast by reducing the background light and increase the resistivity of the storage phosphor layer. The Specification explains the operation of the tube with reference to Figs, 10, 11 (not shown) and indicates that for the phosphor to act as a storage dielectric it should be about 0À001 to 0À003 inch thick, i.e. about one-third the thickness of a conventional C.R.T. screen, and the phosphor layer should be porous with the particles not in good electrical contact. It is suggested that a colour dot screen may be made. Operating details.-(i) The contrast gun may be omitted and the effect obtained by applying a - 10 v. pulse to the cathodes of floodguns for 10% of the time they are on. (ii) The writing speed may be increased when the flood guns are turned off, as by applying a - 200 v. pulse to the control grids (iii) The erase may be improved by pulsing the conducting layer (tin oxide) from +300 v. to +400 v.; reducing to 0 v., and slowly increasing to + 300 v.
